So i would like to know what the difference is between slot ports and aeroports. What are their advantages and disadvantages, are the differences between spl and sq between the two, when should you use one over the other, does the car make the difference in using either one. Enlighten me on this topic please!

As far as efficiency goes, I like to think of it like this...how many round drains do you see vs how many not round drains do you see? Its all about fluid dynamics. I have only built 1 slot ported box so I am heavily biased towards round ports. The only time they create a problem is when you try to adapt a large amount of port area to a small volume, this usually happens when dealing with the high output small cone diameter drivers like the sa8 that are increasing in popularity.

im very heavily biased to aero ports also....theres super easy to install...easy to tune and if u dont like the sound cut 1" off at a time till u achieve ur desired frequency......if u build a slot and u dont like it well ur pretty screwed cuz its not gonna be easy to modify.....and last i checked this sport is all about trial and error.....very rarely do people reach there goal/goals on there 1st build its all about the "TEST N TUNE"!

plus the numbers alone speak for them selves recommended port area for a aero is 7-9 sq.in per cube which is where a slot u need 13+ per.....give or take ur application ....y not save the space and it can be used for increased output

05-28-2012, 01:39 AM

Ive always kind of wondered this myself but i feel like the answer to which is better depends on the situation. I agree with kushy dreams thinking of air flows easier through the aero ports but I feel like there would be some cases where you would be better off using normal slot ports do to space like he said.

It would be interesting to see how a slot port box of the same volume and port length did agaisnt a slot ported box of the same volume and port length in the same environment

It depends on how much port area you need, what the net volume of the enclosure needs to be, what tuning you want, how much trunk space you have, etc.

Slot ports are better for large enclosures. Let's say you're building a box for 2 12s and you want 24 sq in of port area. You can either use 2 4" aeros or a 2 in wide slot port. Since you'll have already bought MDF to build the enclosure and large enclosures don't require much for port length, you'll likely have enough extra MDF to make the slot port (so you basically get the port for free). Or you could by a pair of 4" aeros for around the same price as a full sheet of MDF. Slot ports take a bit of extra work and calculation, but for a large enclosure, the cost savings are definitely worth it.

Aeroports are better suited to small enclosures. Let's say you're building a .5 cu ft (net) enclosure for a single 8" woofer. Since the height of a slot port is dictated by the height of the box, the port area is going to be larger than may be necessary for a small sub (an 8"x1.5" slot port has almost twice the area of a 3" aero). More port area means a longer port length fore the same tuning. A smaller enclosure means more port length for the same tuning. Using a slot port in a small, low-tuned box is going to require a very long port. The mdf used for a slot port also takes up airspace. All of this means that the slot port is going to increase the overall volume of the enclosure by quite a bit, defeating the purpose of buying a small sub suited for small volume. You're also not going to see the same cost savings. A slot port in a small enclosure is going to require a lot more mdf, which will likely mean you have to buy a full sheet. With an aero port, you can use a half sheet, which balances the cost of the port while keeping the overall enclosure dimensions nice and small.

Aeros also have the advantage of ease of use. You just have to cut a hole and mount vs. measuring, cutting, and glueing/screwing in the boards for a slot port. You can also adjust the tuning without ripping the box apart or building a new one.

I have to disagree completely on the ease of use with smaller volume boxes. With a .5ft^3 box tuned to 35hz, a 3" aero is going to need to be 30" long. Have fun buying elbows and more PVC to fit that inside a box or you can have an ugly external aero hanging out of the box, taking up a lot of space. With a slot, you can easily follow the outside of the box and get the port length needed. Also, using a 3" aero that has a ~4.5" diameter flare is going to require a decent sized box just to make sure you have enough clearance with the port/sub being so close. With that 30" custom aero, it's doubtful you can even fit it inside a box(depending on the sub/port orientation that you needed to do) and still keep your .5ft^3 net volume that you'd be after.

Basically, with a smaller box you're going to need a longer port. And using a smaller volume while trying to tune any lower than 35hz with aeros is going to require you to make them a custom length, which adds to the cost as well. It would be much easier to use an aeroport on a lower power, more efficient setup that utilizes a larger than normal box volume. That way you could rely on a shorter port length and not have to worry as much about internal clearances.

Fair enough. I was just throwing numbers out there. And it really depends on what kind of vehicle it's going in. For example, my Mazda3 hatch allows for a 41" wide enclosure. If I go with an enclosure that's 38w x 9t x 6d, I get ~.56 cubes and I need a 25.6" aero for 35hz. I lose 6" of cargo space, which I can deal with, and I don't have to worry about any bends in the port. Or I could have a 7.5 x 1.5 slot port, which would require more than 40" of port length, would require bends in the port, and would take away more cargo space.

Gotcha. Like I said, makes more sense for larger systems. If you're dealing with a smaller enclosure in a daily driver, it becomes less practical.

Go look up the necessary length for a 4inch aero coupled to .75 cu/ft to give tuning of 33hz. You will need 39 1/2 inches of length. Yes there are some people that can make that work, but for the majority of people out there, that is just not feasible. Say you want even better low end extension and want a 30hz tune, the required port length just went up to 48 1/4 inches. Do you get it now?

By comparison the 4cu/ft box with a 6in pvc port that I'm running now has a 14.5 inch long port that yields a tune of 31.75hz.

Its very simple, the more port area per cu/ft the longer the port needs to be. A 4in round port has 12.56 sq in of area, now divide that by the volume of the box, .75 and you have 16.74666 square inches of port per 1 cubic foot of air displacement. Now compare it to the other box with a 6inch port, or 28.274 sq inches of port area with 4 cu/ft of box volume and you have 7.068 sq/inches of port area per 1 cubic ft of airspace.

Now back to the slot vs aero comparison- just google why pipes are round and not other shapes, it is because they flow the most efficient under PRESSURE.

You aren't using an aero, you are using a plain round port. True aero ports have flared mouths.

Kerfs are definitely a step in the right direction, but it all goes back to my pipe theory and that is pipes are round for a reason. Round ports work well up to a certain amount of square inches of opening per cubic feet, after that the necessary length becomes unfeasible for the build. Someone earlier touched on this, but it was worded sort of differently.

05-28-2012, 04:26 PM

I prefer slots...some people think they are bad to use when you wanna do tuning and cut down on the port, but it's not hard at all if you just make it removable (which is very easy to do). I tried out an aero port on my box because I had never used one before but I wish I would have done a slot port instead. Plus, with a slot port it's very easy to adjust port area. With aero ports if you wanna fine tune it you are pretty much stuck with adding a lot of smaller ports to achieve your desired sound (i.e. to get somewhere between 6" and 8" you need 3x 4" ports which is costly).

To me, the main limitation of the aeroport is that it allows for less control of the output. When I mean control, I mean the group delay, excursion, etc. Aeroports are great for SPL designs where compression is the key, but for musical output, slot ports can be manipulated much more easily to obtain a certain response curve. Aeros are great, and if the output matches that of a slot, the audible differences can be tough to point out at times, and for those who do not care to notice those differences, it then becomes more of a personal preference and involving physical limitations that need to be accounted for more so than the acoustical control. I prefer slot ports for that reason mainly. I might write up a blog about this in detail with all of the advantages/disadvantages of each including some that people do not notice to the ear.

As far as tuning goes, normally it depends on the expansion rate and cutoff frequency. The cutoff can be determined by adding the lengths on all sides together and using the distance-frequency formula to get cutoff. You can effectively use the quarter wave cutoff for subwoofer use.

Length is determined by the entire length of the kerf with the port because every inch of it makes a difference. By stoping halfway down, you eliminate the accuracy of the cutoff at full flare and regard the effects it causes on the response. You have to use the entire length and account for the opening at the end of the port. If you stop halfway, you increase the cutoff frequency and cause inaccurate response curves to be calculated.

Tuning can be a figured mean of the constant length into the cutoff frequency. So, a port that is tuned to say 30Hz may be tuned to 27-28Hz with an added flare with a cutoff of about 70Hz quarter wave. The calculations involved in this are too complex to write down and explain here.

I can only go with ports on the outside due to them taking up airspace otherwise. Not sure how to port this box. It's divided also so i need a port for each sub. Have about 12" above the top of the box before i hit the rear slider.

1st off use 3/4 inch mdf then you will have to use external aero ports for you box.

An aeroport with the same port area as a slot port and same tuning should be a smaller box.

Not really. The port is still going to be the same length. It won't be THAT much of a difference.

Yes, sorry I didn't post it yet. This is not meant to be insructional by the way, it is meant as a non-biased opinion and the choice of using either round, slot, or square ports are up the the design limitations, capabilities, and personal preferences of the request. But hopefully it helps a little bit on what I think of each to determine what may work best for you.
The responses I may get from this will either be positive or negative, but I appreciate both just for everyones information. If you feel different than I do on this, feel free to reply to me in email or PM about why you feel that way, or if you have any questions regarding what I have mentioned in the blog.
Remember, it is a blog, and blogs are based mainly on opinion, and from my professional experience of design, my opinion of this should be respected even if different cases have been proven or go against what I have mentioned. Because, the reason they may differ is due to the design and how it relates to the environment and the accuracy of it when calculated, so in reality, the choice is still always your own.

The main point is about limitations and how they can help you decide, if at all, on any of the choices you have, more than saying one is better than the other in acoustics. In pure calculation, differences can and are almost always minor as some may agree. So, don't take the blog the wrong way. And if you do, to bad. :D

Slot port or Aero port? Which should I use??? (http://slotvsround.blogspot.com/)
